In an e-mail to The Chronicle, center Jonathan Goodwin, a pending free agent, said the 49ers have yet to reach out to his agent to broach contract talks. Goodwin, 35, has started all 56 games, including playoffs, since he signed with the 49ers in 2011. …

Baldwin, who was acquired in trade with the Chiefs for another disappointing first-round pick, A.J. Jenkins, before the 2013 season, had three catches for 28 yards with the 49ers.
